Confocal microscopic Raman spectroscopy system

The STARTIN OPTRONICS® fiber-amplification and innovation experiment system measures key erbium-doped fiber amplifier (EDFA) characteristics and helps students understand EDFA principles, construction and functions. Passive components including attenuators, isolators and couplers can form an EDFA test system or be tested individually. An open, compact design uses external fiber patch cords for all measurements, providing convenient operation and protecting valuable components. It is a teaching platform for EDFAs and passive fiber optics.

Laser micromachining is a noncontact, clean, wear-free, high-precision processing technology. Improved laser reliability, computing and optical components have accelerated its development. This training workstation follows current industrial standards to teach laser-marking principles and applications. High-energy beams process predefined patterns precisely. The optical platform accepts various laser brands, with beam shaping before the processing system. Loaded scan paths and suitable process parameters control machining.

The optoelectronic imaging-device characterization and design experiment uses an open, modular structure to demonstrate linear and area-array CCD operation and common engineering tests. It teaches CCD principles and applications. CCD imaging systems are widely used in civilian, industrial and military fields. EMVA1288-based testing measures and corrects quantum efficiency, dark current, linearity, nonuniformity and spectral responsivity. Based on a general industrial inspection/calibration architecture and core components from Labsphere, the system supports inquiry-based laboratory courses in optoelectronics, physics, measurement and control.

Laser-induced breakdown spectroscopy (LIBS) focuses high-energy laser pulses onto a sample. Above breakdown threshold, the high energy density creates a hot local plasma. As it cools, excited atoms and ions undergo electronic transitions and emit characteristic photons. A spectrometer collects spectra, and peak positions and intensities identify elemental composition. The system integrates optical analysis, photodetection and digital analysis, with a laser and supply, focusing optics, motorized sample turntable, fiber-coupling optics and spectrometer. As atomic emission spectroscopy, LIBS offers rapid measurements without sample preparation and in-situ, real-time detection. Applications include metallurgy, environmental monitoring, geology/mining, food, medicinal materials, biomedicine and heritage inspection/restoration. The company supplies microchip solid-state laser components for portable LIBS and custom research and industrial solutions.
